臺灣混凝土橋樑等結構物腐蝕之危機與其防蝕技術之探討

The Corrosion Crisis and the Corrosion Protection Techniques of Reinforced Concrete Structure in Taiwan

本文檢討混凝土橋梁等結構物之腐蝕原因及提出其防蝕之要點，並舉實例說明其構造物之腐蝕現況與不當之結構設計及防蝕設施，導致浪費人力、時間及財力，並減短其構造物之使用壽命，而危害交通公共安全。

This paper discusses the corrosion problem and the corrosion protection method of the corroded Reinforced Concrete (R.C.) structure, and provides some practical instances to illustrate the current corrosion situation of the existed R.C. structure. It is emphasized that we are wasting labour, time, money and decreasing the working life of the existed corroded R.C. structures that are dangerous to traffic and public safety. Improper design of R. C. structure in corrosion environment area and the ineffective method of corrosion protection to the corroded R.C. structure in Taiwan should be improved.
